and ADRIANA AKEMI KUNIY

Summary

The ‘Critically Endangered’ Cone-billed Tanager Conothraupis mesoleuca was described in 1939,based on a single specimen collected in the state of Mato Grosso, western Brazil. Not seen againin the wild until 2003, this poorly-known species was rediscovered in Emas National Park, in theBrazilian state of Goias. We describe here the discovery of a new population of Cone-billedTanager in Chapada dos Parecis, along the upper Juruena River basin, in the state of MatoGrosso. The birds were always detected in (or near) flooded habitats along rivers. At least 40

individuals were found, but the population may be larger, since areas of potential habitat areavailable in the upper Juruena basin and these have not yet been surveyed. We also providehere the first information on the biology and behaviour of the species based on observationsin Juruena and Emas, as well as a first description of the female. Historical documents and ourrecords support our suggestion that ‘‘Juruena’’, i.e. the type locality of the Cone-billed Tanager,refers to the Juruena telegraph station (12

o50’S, 58

o55’W). Considering that the range of the

species is being settled, research on different aspects of its biology are urgent.

O tie-bicudo Conothraupis mesoleuca, ave considerada criticamente ameacada, foi descrito em1939 com base em um unico especime coletado no Mato Grosso. A especie permaneceu semnovos registros ate 2003, quando foi redescoberta no Parque Nacional das Emas, GO.Descrevemos aqui o achado de outra populacao da especie na Chapada dos Parecis, ao longo dabacia do alto rio Juruena, MT. Nossos registros foram sempre realizados em (ou proximo de)ambientes ribeirinhos alagados. Encontramos pelo menos 40 indivıduos, mas a populacao podeser maior, pois existem areas de habitat potencial na bacia do alto Juruena que nuncaforam visitadas por ornitologos.

Introduction

The Cone-billed Tanager Conothraupis mesoleuca (Berlioz, 1939) is a ‘Critically Endangered’(Birdlife International 2008), poorly-known passerine included in the family Thraupidae (Storer

1960, CBRO 2008). It was described based on a single specimen collected by J. A. Vellard in thestate of Mato Grosso, western Brazil. This specimen, a male, is still at the Museum Nationald’Histoire Naturelle, Paris, France (MNHN 1939.796). The only reference to the type locality is‘‘Juruena, northeast of Cuyaba’’ (Berlioz 1939). The exact position of this locality has beenimpossible to trace (Birdlife International 2008).

After the collection of the type specimen, the Cone-billed Tanager was not observed in thewild again until 2003. The rediscovery occurred in Emas National Park (in the Brazilian state ofGoias), when a female of the species was observed for the first time (Buzzetti and Carlos 2005).Since then, the Cone-billed Tanager has been observed regularly in four different sites in EmasNational Park (Birdlife International 2008), which is the only place where the species is known tooccur. Curiously, Emas is c.750 km southeast of Juruena River.

The biology and natural history of the Cone-billed Tanager are essentially unknown.Therefore it was regarded as data deficient in the current version of the Brazilian list ofendangered species (IBAMA 2003). Clearly, more information is needed to better define itsconservation status, understand its life history, as well as to determine possible conservationstrategies to protect this unique species.

In this article we: i) report on a new population of the Cone-billed Tanager that we found in theupper Juruena River basin, Mato Grosso, Brazil; ii) present information on several aspects ofits biology (habitat associations, abundance, behaviour, diet, morphology, vocalizations, andsystematics), as well as provide a description of the female; and iii) describe and justify theestablishment of the true source of the type locality based on previously unused historicaldocuments.

Methods

Study area

The Juruena River, part of the Amazon basin, is a main tributary of the Tapajos River. Its upperreaches are in the Chapada dos Parecis (Parecis plateau), in the state of Mato Grosso, in westernBrazil (Figure 1A and B). The upper Juruena basin, located in the southern part of an ecotonebetween the Amazon and Cerrado regions, comprises a mosaic of natural and anthropogenichabitats (Souza and Martini 2000) such as: typical and dense savannas (cerrado sensu stricto andcerradao); gallery forests (mata de galeria and mata ciliar); flooded forests; and small patches ofmarshes of flooded grasslands with scattered shrubs and Moriche Palms Mauritia flexuosa(vegetacao aluvial herbaceo-arbustiva) along rivers. Anthropogenic habitats include extensiveand mechanized plantations of soybean, corn, sugarcane and cotton. Annual rainfall rangesbetween 1,400 and 2,000 mm, with a marked dry season between April and September (Rosa etal. 2007).

Data collection

Following our first record of Cone-billed Tanager in the upper Juruena River (see results) weinitiated playback surveys looking for the species throughout Chapada dos Parecis and other areasin central and eastern Mato Grosso: Sao Jose do Rio Claro, Brasnorte, Tangara da Serra, Tesouroand Barra do Garcas (Figure 1B). Playback trials (n 5 146) were carried out at random in places(sampling points) accessible by boat, car or trail. During trials we broadcast a male’s loud song(recorded during our first encounter with the species – see results) for 5 minutes followed by5 minutes of silence. Then we noted: i) presence or absence of the species, ii) the habitat type(cerrado savanna, flooded forest, gallery forest, or flooded grassland), and iii) the geographiccoordinates using a GPS (c. 5–15 m precision). Minimum distance between sampling points was750 m.

We tested the null hypothesis that the species did not select specific habitat types, i.e. that ituses habitats by chance as they were available. We performed a randomization test analogous tothe chi-square in Ecosim 7.72 (Gotelli and Entsminger 2009), in which the expected matrixwas randomized (rows and columns) 1,000 times, and a chi-square deviation statistic for eachsimulated matrix was calculated. We then used the distribution of these deviations to calculate

the probability of obtaining our observed matrix if the null hypothesis is correct (Gotelli andEntsminger 2009). To avoid biasing the results by including as available habitat areas that werenot actually available to the species (Jones 2001), we used in this analysis only sampling pointslocated within a 3 km-radius buffer around each Cone-billed Tanager record. We arbitrarilydefined buffer size since no information about dispersal or home range of the Cone-billed Tanageris available.

We also report here ‘‘passive’’ records, i.e. capture, sightings, or aural records made without theuse of playback, as well as records made by collaborators. Once the species was encountered, weobserved and noted aspects of its behaviour and biology. Recordings of vocalizations of the specieswere made on several occasions with shotgun microphones and tape or digital recorders. Playbacksurveys and observations were carried out in Mato Grosso from September 2006 to May 2008.Additional observations on the species’s behaviour and biology were also carried out in EmasNational Park in December 2007.

To trace the exact position of the Cone-billed Tanager’s type locality we consulted books andhistorical documents not reviewed in the ornithological literature in an attempt to find the routeof J. A. Vellard, the collector of the type specimen.

Results

Cone-billed Tanager records

On 20 September 2006, CCG recorded a loud and unknown song on Juruena riverside (site 13

in Figure 1C). The bird was attracted by song playback, photographed, and identified as a maleCone-billed Tanager following a picture available in Buzzetti and Carlos (2005).

We registered the species in 18 sites in Chapada dos Parecis region, near Sapezal, Campos deJulio and Campo Novo do Parecis (Figure 1C). Among these records, 14 were made by playback(see Appendix 1 for details). Only two records were made outside the Juruena River: one in thePapagaio River, c.1.2 km upstream of the Utiariti waterfall (Tirecatinga Indigenous Land - site 5

in Figure 1C) and another in its tributary, the Verde River (site 17 in Figure 1C). No records weremade outside Chapada dos Parecis region.

Additionally, two birds were mist-netted on Juruena riverside during a parallel bird survey.A male was captured on 15 December 2006 by CCG between gallery forest (mata ciliar) andcerrado savanna (site 11 in Figure 1C). The bird was banded (CEMAVE aluminium band,number E72436), measured (see below), photographed (Figure 2) and released at the capture site.On 4 October 2006 a female was captured (site 13 in Figure 1C) by E. Santos. The bird wasphotographed (Figure 3) and collected as a part of the field study, and only later identified asa female Cone-billed Tanager. This specimen was deposited at the Museu de Zoologia daUniversidade de Sao Paulo (MZUSP 76674; see description in below).

Habitat and abundance

Cone-billed Tanagers were always found in or near (, 120 m) flooded habitats along rivers,such as seasonally flooded forest or flooded grassland with scattered shrubs and Moriche Palms(Figure 4). The randomization test rejected the null hypothesis of no habitat selection by theCone-billed Tanager (n 5 74 sampling points, v2 5 21.6, P , 0.025). Flooded habitats appear to bepreferred by the species, whilst cerrado savanna and gallery forest appear to be avoided (Table 1).The Cone-billed Tanager was also observed in flooded habitats at Emas National Park (Buzzetti2006, De Luca pers. comm. 2007, LFS pers. obs.). These findings suggest that the preferredhabitats of the species are flooded or seasonally flooded riverside areas. However, based on thereport of the type specimen’s collector, and also by analogy with its congener, Black-and-whiteTanager Conothraupis speculigera, the favoured habitat was described in the literature as ‘‘arid


forest or scrub’’ (Berlioz 1946, Storer 1960), or ‘‘bushy vegetation among dry forest’’ (Isler andIsler 1987). These earlier descriptions suggest cerrado, which is the dominant physiognomy ofthe Chapada dos Parecis. Thus, if the species really selects flooded areas, those habitatdescriptions may have delayed the rediscovery of the species by leading researchers to look inthe wrong habitats (Buzzetti 2006).

Although the Cone-billed Tanager is strongly responsive to playback (CCG and LFS pers. obs.),it was found in only 14 of 146 playback sampling points. We believe that this could suggestlow population density. However, accurate population size estimation will require even moreintensive effort in the appropriate habitat types. Here we found around 40 individuals (see

Appendix 1), but several areas of potential suitable habitat exist in the Chapada dos Parecis thathave not yet been visited by ornithologists; therefore population size could be larger. These areas,comprising a mosaic of private and indigenous lands, are prime targets for new surveys (seediscussion).

Behaviour and diet

The Cone-billed Tanager is apparently territorial and solitary or monogamous, as all sightingsthat we made were of pairs or single males (n . 60, considering repeated sightings in the sameplaces). Males respond strongly and quickly to playback, flying repeatedly over the playbacksource, suggesting territorial defence. Females also respond to playback, but do not approach asclosely as males. The Cone-billed Tanager was never seen by us to join monospecific or mixedspecies flocks, as is common among many tanagers in the Cerrado region (Isler and Isler 1987).

Both sexes may perch at the top of trees, or more commonly below 5 m in shrubs. Duringfeeding, birds were observed taking small flying insects in rapid sallies to and from the sameperch. Also, surprisingly, they were very often observed eating seeds, including bamboo andexotic grasses (such as Brachiaria sp.), consumed in a similar way to Sporophila seedeaters.

Morphology

Measurements of the two captured birds as well as of the type specimen are presented in Table 2.The male we captured displayed signs of neither moult nor brood patch, but rather was in fulladult plumage. Rictal commissures were visible (Figure 2), which usually indicate relativelyrecent fledging in volant birds (Ayala et al. 2007). Thus this male was a sub- or young adult. Thissuggestion is supported by the bill, dark-coloured at the tip (Figure 2). Full adult males haveentirely bluish-grey bills (Buzzetti and Carlos 2005, CCG and LFS pers. obs.), while young malesseem to have dark-coloured bills, as suggested by a picture available on the Pantanal Bird Clubwebsite (http://www.geocities.com/TheTropics/Cabana/6292/rhynchothraupis.jpg).

The type specimen has a dark bluish, white-tipped bill (LFS pers. obs.), that could beinterpreted as a subadult character. Nonetheless, young males apparently change bill colourfrom the base to the tip, from dark to light bluish-grey (compare Fig. 2 with the picture in the linkabove). Hence, we support the hypothesis that the type specimen is an adult whose bill colourchanged after collection and before Berlioz analyzed it, since he described it as bluish-grey(Berlioz 1939).

The female collected on 05 October 2006 (Figure 3) had some moulting on the head, back andunderparts. Brood patch was not reported by the collector of the specimen. Following the Munsellcolour system (Munsell 1976), the colour of the female was: upperparts, wings and tail darkgreyish brown (10YR 3/2), lighter in the auriculars; throat brown (10YR 5/3), breast, flanks, andundertail coverts dark brown (10YR 3/3); belly light yellowish brown (2.5Y 6/3), bill and tarsidark brown; tail rounded and tail feathers slightly pointed (see Table 2 for measurements).

Vocalizations

The song of the Cone-billed Tanager is loud and characteristic, apparently sung exclusively bymales (Buzzetti 2006, CCG and LFS pers. obs.). Females and males were observed emittingone-note calls, similar to those of the sympatric Silver-beaked Tanager Ramphocelus carbo, butslightly more metallic.

Four voice samples of males from Juruena were compared with four from Emas National Park -ENP (recordings are in the Elias Coelho Sound Archives, ASEC, Rio de Janeiro, and The BirdSection Archives of the MZUSP). A comparison of the spectrograms (Raven 1.2.1, BioacousticsResearch Program, Cornell Laboratory of Ornithology) suggest that loud songs of birds fromJuruena are slower than those from ENP. They also descend and end with a metallic, bisyllabic‘‘tzi’’ (Figure 5a). The faster ENP songs end with a quick (~ 0.5 s), strong, and ascending note

(Figure 5b). Perhaps songs are merely local dialects, since plumages are apparently the same inboth places. If these two populations are indeed disjunct, then this species can provide interestinginformation about local isolation and micro-evolutionary processes. Clearly, more informationis needed to reveal differences and similarities between the two populations.

Systematics

General behaviour, including vocalizations, along with the unexpected diet and foraging behav-iour for a tanager, suggest that taxonomy of the Cone-billed Tanager must be re-evaluated.Morphological, vocal, and molecular characters are needed to determine the relationships of thisspecies: whether it is indeed a tanager (family Thraupidae) or an emberizid (Emberizidae, finchesand allies), as suggested by Storer (1960). Since the specimen collected at Juruena was preparedbefore we analyzed it, it is not possible to quickly eliminate Emberizidae as a possibility based onpalate structure.

Additionally, the relationship between the Cone-billed Tanager and its congeneric Black-and-white Tanager C. speculigera must also be re-evaluated. For instance, we noted strong similaritiesbetween the Cone-billed Tanager and the White-naped Seedeater Dolospingus fringilloides(Emberizidae), a poorly known finch which lives in flooded forest (e. g. IAVH 11259, ‘‘bosqueinundable’’) and in similar habitats in northern Brazil, southern Venezuela and eastern Colombia.We examined seven specimens of White-naped Seedeater, two specimens of Cone-billed Tanager,and one Black-and-white Tanager (see Appendix 2 and Acknowledgements). There is a strongsimilarity in the plumage of the females of White-naped Seedeater and Cone-billed Tanager,which is brown in both species. On the other hand, Black-and-white Tanager females have olive-yellow in the upperparts and pale yellow in the underparts (see also Isler and Isler 1987).Moreover, measurements (wing, tail, bill, and tarsus - available upon request), bill colour andshape, and especially the tail shape of Cone-billed Tanager and White-naped Seedeater areremarkably similar, suggesting that the Cone-billed Tanager could be closer to the White-napedSeedeater than to the Black-and-white Tanager. Nonetheless, whether these similarities are relatedto common ancestry or to convergence should be assessed by detailed phylogenetic analysis.

Tracing the type locality

The only reference to the type locality of the Cone-billed Tanager is ‘‘Juruena, northeast ofCuyaba’’ (Berlioz 1939, 1946). Juruena is the name of a large river northwest (not northeast) ofthe city of Cuiaba, as it is now spelt. To the best of our knowledge, no other ‘‘Juruena’’ localitywas known in that period. Noting this discrepancy, F. Pacheco in Sick (1997: 736) suggested that‘‘Juruena’’ might be interpreted as the region of the Juruena headwaters, in the Chapada dosParecis (Parecis plateau) - about 100 km northeast of Vila Bela de Santıssima Trindade (thereforenorthwest of Cuiaba). Thus, the true position of the ‘‘Juruena’’ of Berlioz (1939) is unclear, as itseems that the original description of the type locality is erroneous. It is unclear as to whom theerror should be attributed - J. A. Vellard, the collector of the type specimen, or Berlioz, whodescribed it (Weidensaul 2002).

No other published records exist in the ornithological literature that describe either Vellard’swork or his route when he collected the Cone-billed Tanager type specimen, hence the confusion.However, we found information about Vellard in historical documents. In 1938 he joined thefamous ethnographer Claude Levi-Strauss in the expedition to the Serra do Norte (northernmountains). This expedition is considered the last great ethnographic expedition of the twentiethcentury and was reported in the famous book Tristes Tropiques (The Sad Tropics; Levi-Strauss1955). Yet, the name Vellard is seldom cited in that book, without indicating his role in theexpedition. That information only became available upon the publication of the field journal ofCastro Faria, a Brazilian anthropologist also on the expedition (Castro Faria 2001). That journalproved valuable, since it included a detailed, daily-based description of the expedition route,including the role played by Vellard.

Vellard, an expert in spider taxonomy and toxins (Vital Brazil 1991), was the naturalist andphysician of the expedition (Domingues et al. 1998, Castro Faria 2001). He published an articledescribing the production of curare poison by the Nambiquara Indians that he observed duringthe expedition (Vellard 1941). Perhaps that he was not an ornithologist explains why he did notpublish the list of the bird specimens that he collected there, but rather sent them to France forthat purpose.

The route of the Serra do Norte expedition followed the telegraph line built by the RondonCommission (Levi-Strauss 1955) to link Cuiaba and Porto Velho (Diacon 2004). The line, finishedin 1915, crossed a wild and isolated region approximately the size of France, at that time inhabitedonly by native tribes (Levi-Strauss 1955). This was the only route through the region until 1960

when the Brazilian highway BR-364 was built (Costa 2002). According to Castro Faria (2001),Vellard was camped in the Juruena Telegraph Station on 25 August 1938, the date on which theCone-billed Tanager type specimen was collected (Berlioz 1939). We visited that locality (site 2 inFigure 1C) and found at least two individual Cone-billed Tanagers in June and September 2007.Thus, we argue that the Juruena Telegraph Station (12

o50’S, 58

o55’W; Figure 1C) is the locality

described as ‘‘Juruena’’ by Berlioz (1939), i.e. the type-locality of the Cone-billed Tanager.It is located about 266 km northeast of Vila Bela and 488 km northwest of Cuiaba (Millard 2005,Figure 1B).

Discussion

Although we provide the first information on the biology and behaviour of the Cone-billedTanager, the species remains poorly known. There are many aspects of its natural history thatdeserve detailed quantitative studies, such as geographic distribution, population size, habitat usepatterns, reproduction, and taxonomic relationships. Possible nomadic tendencies should also beinvestigated.

In order to better understand the distribution limits and population size of the species, wesuggest additional areas of the Cerrado biome (as well as its ecotones) to be surveyed: thetributaries of the upper courses of Juruena, Arinos, Teles Pires, Xingu, Araguaia, Ji-Parana and


Aripuana rivers, as well as the tributaries of the right bank of the Paranaıba and upper Paranarivers in the states of Goias and Mato Grosso do Sul. Flooded habitats should be the main targetfor these surveys, but other habitats should be visited as well.

Our results suggest that the Cone-billed Tanager has a low population density, and would bea naturally rare species. Such a pattern is likely to be related to habitat selection. If the Cone-billed Tanager does select flooded areas along rivers, its habitat would be linear and naturallyfragmented, since patches of flooded habitat are not continuously distributed along rivers (CCG,pers. obs.). Thus, Cone-billed Tanager’s low population density could be related to the naturalrarity of its habitat. If this scenario is correct, habitat loss would be the main threat to the species.

The extension of potential habitats in the upper Juruena basin, along with the relatively largenumber of individuals found there, suggest that Juruena may currently be a ‘‘stronghold’’. Thus,the effective protection of Cone-billed Tanager habitat in the upper Juruena basin is essentialto protect the species. Because the Cone-billed Tanager is considered to be globally ‘CriticallyEndangered’ (BirdLife International 2008) and because part of its range in Juruena is becomingsettled, more detailed and quantitative research on the species should be carried out as a matterof urgency. Only with this information will we be able to accurately determine its status anddesign effective conservation strategies to conserve this rare and beautiful bird.
